Hairbrush



Patented Dec. 22, 1931 UNITEDQSTATES param' YoFFlcE JOSEPH BORN, F SAN FRANCISCO, CALIFORNIA., ASSIGNOR 0F ONE-HALF TOv JOSEPH VlOSl-IFRIISON, 0F GERLACH, NEVADA HAIRBRUSH Application filed July 7,

My invention relates to improvements in hair brushes, and it consists in the combinations, constructions and arrangements hereinafter described and claimed.

An object of my invention is to provide an improvement over that form of the device shown in my co-pending application Serial No. 432,845 filed March 3, 1930. In said application I show a power hair brush consistl ing of an endless belt with bristles, the belt being driven by a source of power such as an electric motor. In the present form of the device I drive the endless belt by means of a flexible shaft which permits the actuating motor to be supported by some other means than by the hand of the operator. This lightens the device.

A further object of my invention is to provide a device of type described which makes use of an elasticbelt having inclined edges that act as a protecting cover for the operating parts. This prevents the hair from becoming entangled in the working parts during the operation of the device.

Figure 1 is a top plan view of the device with the endless belt removed,

Figure 2 is a longitudinal section through the device showing the belt in place,

Figure 3 is a section along the line 3-3 of Figure 2, and

Figure 4 is a section along the line 4-4 of Figure 2.

In carrying out my invention I provide a forked member 1 (see Figure l) having a hollow sleeve 2 which is preferably non-cirl cular in cross section 'as shown in Figure 4. 5 Within the sleeve I slidably mount a non- A further object of my invention is to 17930.' serial no. 466,304.

in the ends of the rollers 6 and 7 respectively. The purpose of the grooves will beherein- 'after described. I Y

The forked member 1 has slots 12 therein (see Figure 1) for slidably receivingbolts 13 or other suitable fastening means that secure bearings 141 to theforked member. Lugs 15 arecarried by the forked member, and screws 16 are threaded through the lugsv and abut against the bearings 141.' The bearings'car'ryl a 'shaft 17 which in turn carries the roller 6. The screws 16 permit afine adjustmentfof ltghe oller 6 with respect to the forked mem- The forked member 5 carries bearings 18 Vwhich in turn lcarry ashaft 19 upon which the roller 7 is mounted. A `flexible shaft 20 connects with a sourceof power such as a motor (not shown), and this shaft is Vremovthe shaft 20 will cause the roller 7 to rotate.

In Figure 2 I show an endless elastic belt 21 passed around the rollers 6 and This belt carries bristletufts 22. In Figure 3 I show the belt as being provi-ded with a centralrib 23 that enters the grooves 8 and 9. I further show other Vribs 24T-24 4that enter the grooves lll- 10V and 11-11 in the rollers Y6 `and T. Thebelt21 is alsorprovided with inclined edge portions or aprons 25 and 26 that extenditoward each other for substantially closing the opening between the two sides of the endless belt. The inclined rubber portions 25 and 26 protect the moving parts and prevent hair from getting entangled with these parts. The elasticity of the belt permits the inclined portions to bend back upon themselves when the middle portion of the belt passes around either one of the rollably secured to the shaft`19. The rotation of ers G and 7 Without the belt buckling up at these portions.

F rom the foregoing description of the various parts of the device, the operation thereof may be readily understood.

An adjusting nut 27 is rotated on the screw shank 4 so as to permit the rollers 6 and 7 to be moved close enough together to permit the belt 2l to be placed upon the rollers. rlhe nut 27 is then rotated for causing the rollers 6 and 7 to engage with the belt in the manner already described. If a fine adjustment is needed, the screws 16 may be regulated.

The device is preferably used in barber shops Where it is desired to brush and massage the scalp at the same time. The belt latter and the frame.

21 is made removable from the device in order c that the bristles may be sterilized each time the device is used. A handle 28 connects with' the member 5, and by means of this handle theoperator can move the device over the scalp. The device is extremely simple in construction and is durable and efficient for the purpose intended.

Although I have shown and described one embodiment of my invention, it is to be understood that the same is susceptible of varions changes, and I reserve the right to employ such changes as may come Within the scope of the claims hereto annexed.

I claim:

l. A hair brush comprising a pair of rollers spaced apart, an endless belt disposed on the rollers and carrying bristle tufts, the edges of the belt being inclined for provid-- ing aprons which extend toward each other from the opposing sections of the belt and serving as guards over the rollers.

2. A hair brush comprising a frame, means for adjusting the length of the frame, a roller carried by each end of the frame, and an endless bristle-carrying belt disposed around the rollers and enclosing the latter and the frame.

8. A hair brush comprising a pair of rollers arranged in spaced relation, an endless belt disposed on the rollers and carrying bristle tufts, the edges of the belt being inclined for providing aprons Which extend toward each other from opposing sections of the belt and serving as guards over the rollers, and reinforcing ribs carried by the belt at the junction of the aprons and the belt sections.

4. A hair brush comprising a frame, rollers carried by the ends of the frame, a belt passed around the rollers and carrying bristle tufts, said belt having inclined edges providing aprons which extend toward each other from opposing sections of the belt and substantially closing the opening between the sides of the belt and serving as guards over the rollers, and a handle secured to the frame Y and extending between the margins of the aprons.
